Correct musb_read_fifosize() and musb_configure_ep0() functions
for the #ifndef BLACKFIN branch when the silicon uses static FIFO
configuration.  (Most current silicon configures this controller
to use dynamic FIFO configuration; some parts from ST don't, like
the STM STA2062.)

The current MUSB host code doesn't make use of all the available
FIFOs in for periodic transfers since it wrongly assumes the RX
and TX sides of any given hw_ep always share one FIFO.

Change:  use 'in_qh' and 'out_qh' fields of the 'struct musb_hw_ep'
to check the endpoint's business; get rid of the now-unused 'periodic'
array in the 'struct musb'.  Also optimize a loop induction variable
in the endpoint lookup code.

(Based on a previous patch from Ajay Kumar Gupta <ajay.gupta@ti.com>)

Some config registers are not avaiable in Blackfin, we have to comment them out.

v1-v2:
 - remove Blackfin specific header file
 - add Blackfin register version to musb_regs.h header file

Without it, in platforms that don't provide irq_chip.set_wake(),
like omap, musb will WARN() on driver removal.

Fix three omissions in the "mode" sysfs attribute support:
  (a) inability to report errors;
  (b) no DaVinci support ... just report an error;
  (c) for omap2430, accepting unsupportable values

The 2430 stuff is still odd....

Drivers should not add procfs. The functionality in the old
procfs file will be moved to debugfs.

Use platform_data to pass musb configuration-specific
details to musb driver.

This patch will prevent that other platforms selecting
HAVE_CLK and enabling musb won't break tree building.

The other parts of it will come when linux-omap merge
up more omap2/3 board-files.

This patch adds support for MUSB and TUSB controllers
integrated into omap2430 and davinci. It also adds support
for external tusb6010 controller.
